Faster, safer mooring for the world’s biggest ships – all thanks to Dyneema®-based mooring ropes. That’s the reality enjoyed by COSCO, whose vessel the COSPEARL LAKE used the same 22 mooring lines for more than 10 years, even as it logged 11,200 mooring hours on its voyages around the world.
Synthetic ropes made with Dyneema® SK78 fiber have proven to be a game-changer for COSCO, far exceeding the five-year average lifetime of steel wire ropes. In breaking tests conducted in 2018, the COSPEARL LAKE’s mooring lines retained 87% of their original 130-ton strength more than a decade after they were first installed on the vessel.
A decade of delivering
Over 10 years, lines made with Dyneema® fiber have exceeded our expectations, bringing clear benefits in lifetime performance, efficiency, and safety. We’re delighted to extend our relationship with our partner Avient and to use mooring ropes made with Dyneema® SK78 fiber on even more oil tankers.

Dyneema® enables faster and more profitable operations
Stronger on safety
Contributing to cleaner seas
We’re very proud of our partnership with COSCO. The relationship was forged in the success of the original trial and the installation of Dyneema®-based mooring ropes onboard the COSPEARL LAKE back in 2007 – and it’s testament to both our Dyneema® technology and COSCO’s application of it that the mooring ropes continued to perform so well for so long. We hope to continue delivering outstanding performance for COSCO vessels for many more years.

A strong case: Why choose mooring ropes made with Dyneema® fiber?
Minimal loss of performance: after 10 years in action, breaking tests on the COSPEARL LAKE’s spring lines showed a residual strength of 114 tons, 87% of their original 130-ton strength.
Seven times lighter: mooring ropes made with Dyneema® fiber are seven times lighter than steel wire ropes of the same strength and diameter.
Much faster docking: ropes made with Dyneema® fiber cut the vessel’s docking times from an average of four hours to just 70 minutes.
Improved health and safety: because mooring ropes made with Dyneema® are lightweight, soft, and flexible, there have been no reported line-related hand, wrist, or back injuries on the COSPEARL LAKE.
Better for the environment: unlike steel wire alternatives, ropes made with Dyneema® fiber don’t need grease, lubricants, or associated cleaning products, which helps to limit pollutants entering the ocean.
